sweet game! i would have rated it higher, if i didn't beat portal 2 before making this review.
a fun puzzle game
For a 2007 game, this title aged incredibly well. Great atmosphere, great puzzles, great replay value.
It really does feel like a tech demo when you step back and look at it, although that's necessarily a bad thing.

short and sweet and easy and cool
Classic puzzler with well designed puzzles with a well written story backing the whole thing up. I'd recommend this to anyone.
